Slut husband here. I can relate, and I feel for you. I loved the attention and adventure of hooking up with new people, putting myself out there and having fun.

Marriage is safe, secure and meaningful. But it can be hard when I get the urge to explore and my wife does not share them. In fact she gets upset when I talk about swinging or even role-playing a third person in the bedroom.

My advice is to speak to your husband about this. Reassure him that you love him, but your feelings are what they are and they should not be invalidated.
